T0 @ZZ whom, it may concern: 1

Be it known that I, 'JOHN lvL'CAMERoN, a citizen of the United States, residing at Philadelphia, in the -county of Philadelphia and State of Pennsylvania, have invented a new and useful Slow-Closing Valve for Flushing VVater-Olos'ets, Urinals, 85o. of which the following is a speciiication, reference being had to the accompanying two sheets of drawings,

in which- Figure lis a surface elevation of the in-A vention. Fig. 2 is' a plan view. Fig. 3 is a vertical section. Fig. 4t is a vertical section of the slow-closing valve, andFig. 5 is a transverse section of the puppet-valve elon gated stem.

Similar letters refer to similar parts inthe several views.

The valve-casing A consists in the upper and enlarged water-.pressure chamber B, which is provided with a screw-cap d and an exterior water-channel b from a water-supply, a reduced valve-chamber C,whose connection with the chamberY B forms a Valve? seat c, a lifting-toe chamber d being formed exteriorly of it, a globular chamber D intoy n7' 7c of said valve H is a uted or water-passage spindle Z of a puppet-valve I, which seats on and closes the top port j, being held in place by a weight J, which embraces the reduced and extended end m of the spindle Z and bears on the top of said valve, while the bottom of the slow-closing valve H seats on the valve-seats and opening E of the partition K, which separates the water-supply nozzle G from the ilushing-pipe L. The bottom end of the puppet-valve spindle Z projects far enough below the bottom of the valve H for the application of means for lifting it. To that end a chamber M is formed transversely of the valve H for the action of said lifting means, while thevalve closes on the valve-seats@ e.V

A screw-shank N of the valve H is provided with a conical nut O and depending jaws P, in which is pivoted the stem Q of a' preferably leather cup or water-cushion piston R, between the upper and lower washers n c and jam-nut p on thescrew end of the shank N. Said piston reciprocates in the cylinder S, which extends upwardly from the screw-cap T of the bottom chamberF,in which a waterpressure channel q is formed for making an upward water-pressure against the bottom of the piston R. v

To control and regulate the volume of water flowing through the exterior-'channel to the top and water-pressure chamber B and the interior channel q of the cap T, like regulating valves or plugs-U. U are employed, each consisting, preferably, in a plug r, which screws through a stuilng-box s of the cap T into the channel q, and thus restricts or entirely closes it and the water ilow.

A rod V,' operated by an exterior handle t, extends through and is journaled in the sides of the exterior toe-chamber d. It is provided with a lifting-toe u, which is located and has a vertical vibration in the chamber M of the valve H, where it contacts with the bottom of the puppet-valve stem L and the valve H for lifting them.

When the lusher requires repairing, the valve H is gradually raised and the arm t gradually turned until the lifting-toe u takes into the exterior chamber d, after which said valve H and its connected parts can be lifted out of the casing by removing the screw ends or caps a T.

The operation of the valve is as follows: Water enters the casing through the nozzle G into the globular chamber D, and passing through the channel b iills the upper chamber B and serves as a pressure in keeping the slow-closing valve H on its seats c e. It also passes by the flexible cupped piston R to lower end, pressing upwardly against the bottom of said piston. The top area of the valve H exceeding that of the bottom, the water-pressure keeps the valve closed on its seat c and vthe piston R a't the bottom of its stroke. To open IOO the valve H for flushing, the handle t is depressed, when its toe u vibrates against the bottom of the spindleZ and opens the puppet-valve I, by which the waterpressure above the valve II is drained off through its portsj 7a into the toe-chamberM and the flushing-pipe L. An additional depression of the handle or lever t causes the toe to vibrate against the bottom of the slow-closing valve H, lift it from its seats c e, and the Water to ilow from the supply-nozzle G through the valve-seat c and out at the iushing-pipe L. The valve H is prevented from opening too rapidly by the valve or plug U in the channel b, which restricts the water flow. If the channel-How b is greater than the ports j 7o, they will not drain and relieve the valve H of the top water-pressure. Consequently it will remain closed. The conical nut C is to gradually close valve-opening so as to give the required afteriill.

The closing of the valve I-I on its seats c e after the removal of the top pressure is controlled by the plug-valve U. V'Vhen said valve II rises, it carries the connected Watercushioned piston R with it, which creates an increased water-space beneath said piston. The speed of closing depends upon the discharge area through the channel q, which is regulated by the plug-valve U. lf it is partially open, the water will discharge and the piston descend accordingly, but if closed the water cannot escape and the piston R descend. Consequently the valve II must remain open. It will be readily seen that the descent and closing of said valve H depends upon the bottom valve U, which chokes the ilow of Water from beneath the piston R, restrains its descent, and regulates the closing of the valve H.

I claiml. In a lusher, the combination of a lushercasing; an exterior lifting-toe chamber, a sloW-closin g valve,a sloW-closing-valve chamber, an exterior Water-channel for producing a water-pressure on the slow-closing valve, a puppet-valve of the slow-closing valve, and a vibrating toe for operating the slow-closing and puppet valves and which folds into the lifting-toe chamber out of the line of the valve travel when said valves are removed for repairs, for the purpose shown and described.

2. In a ilusher, the combination of a Ilushercasing, an exterior lifting-toe chamber, a slow-closing valve, a slow-closingvalve chamber, a puppet-valve of the slow-closing valve, a Water-cushion piston-cylinder at thc bottom of the flusher-casing, a Water-cushion piston of the water-cushion cylinder, connecting stem between the slow-closing valve and the watercushion piston, and a vibrating toe which operates the slow-closing and puppet valves and folds into the exterior lifting-toe chamber, for the purpose shown and dcscribed.

In testimony whereof I ailix my signature in presence of two Witnesses.
